sired to change the coils of the machine and` put in longer or shorterones the same supporting means may be adapted to the particular use bymoving the rings 19 and 20 axially of the machine by rotating the nuts24. In this particularl arrangement the insulating rings have been drawntogether by bolts 21 and the rings connected and supported by the studs22 at points circumferentially spaced and between the points at whichthe bolts 21 are located.

In a modilication of this invention, we have provided segmental bracingmembers 25 to take the place of the bolts 21. These .Y bracing plates 25are preferably hook shaped and the end of the hooks provided with a longbody portion 2G, which extends circumferentially of the machine and uponwhich the end turns 18 rest, the other part of the hook extendingradially. The other end of the retaining members are provided withelongated openings 27 which receive the studs 22. This end of theretaining member is also provided with a tapped portion for thereception of a set or adjusting screw 28, by means of which theretaining members may be clamped and also adjusted radially of themachine, thereby drawing up or lowering the end turns of the statorwinding.

Interposed between the body portion 26 of the retaining member and theend turns is a flexible insulating ring 29. Supported by the studs 22and interposed between said studs and the end turns 18 is preferablyanother insulating ring 30. As in the first case, the insulating ringsare adapted to be shifted axially of the machine to change the point atwhich the end turns are supported. The bracing members 25 are adapted tobe shifted at the same time that the insulating supporting rings are,thereby providing bracing means which has an axial and also a radialadjustment. As in the lirst case, the axial adjustment is accomplishedby moving the nuts 31 lengthwise of the studs 22.

At one end oi each ot the body portions 26 of the bracing members is atongue or projection 32 which engages a slotted or grooved portion 33 inthe body portion of the adjacent bracing member. It is therefore seenthat each bracing member has at one end of its body portion a tongue orprojection 32 and a slotted or grooved portion at its other end. Whenall of the bracing plates are set in position and adjusted properly,each slotted or grooved portion 33 has locked within it a tongue orprojection of its adjacent bracing member. In this way a flexiblesupport is provided for the end turns of the stator Winding and onewhich is capabie of radial and axial adjustN ment.

This means of supporting the end-turns of the stator winding is simpleand inex-n having a laminated core, end heads for re-l taining saidcore, windings on said core having extending end portions, su portssecured to said end heads, and means held in operative position throughthe medium of said supports and having both radial and axial adjustmentrelative to said end heads and effective in adjusted position to securesaid end portions.

2. In a dynamo-electric machine, a core provided with a winding havingextending ond portions, means for supporting and securing said endportions relatively to said core, said means having both radial andaxial adjustment to provide a plurality of effective securing positionstherefor.

3. .In a dynamo-electric machine, the combination of a stator havin alaminated core and a Winding with en turns, end heads supporting saidcore, means for supporting said end-turns relatively to said corecomprising members secured to said end heads and extending outwardlytherefrom, and inter-fitting tongue and groove members axiallyadjustable and sup orted from said outwardly extending mem ers.

4. In a dynamo-electric machine, the combination of a stator comprisinga housing, a laminated core having a winding with end turns, said coresupported by said housing, end-heads holding said laminated core inposition, members projecting from said endheads, and radially andaxially adjustable bracing members having interritting tongue andgrooved portions and for supporting the end turns of said Winding, someof said bracing members being mounted on said projecting members.

5. In a dynamo-electric machine, the combination of a stator comprisinga core and a winding therefor having end-turns, and means for supportingsaid end-turns including segmental members adapted to engage theradially inner side of said endturns and having radial extensionssupported from said core, said segmental members being relativelyadjustable.

6. In a dynamo-electric machine the combination of a stator having alaminated core, end-heads ior retaining said laminated core, windingshavin end turns, and carried by said core, stu s secured to andprojecting from said end-heads, and a plurality of bracing membershaving intertting niemeer,

' turns of said winding, and means for adjusting said bracing membersradially and axially of the machine.

8. In a dynamo-electric machine, the combination of a stator having acore provided with windings with end turns, interitting bracing membershaving hookshaped portions circumferentially spaced for retaining saidend-turns in any desirable position, and supporting members upon whichsaid bracing members are adjustably mounted.

9. In a dynamo-electric machine, the combination of a stator comprisinga core having coils with projecting end-turns bracing members havingradially and circumferentially extending portions for holding the endturns of said coils in any desired position, and supporting members uponwhich said bracing members are radially and axially adjustable, saidcircumferentially extending portions having tongue and. grooved portionsfor fitting into and receiving respectively the grooved and tongueportions of adjacent bracing members.

i0. In a dynamo-electric machine, the combination or' a stator having acore provided with a winding having end turns, and interttinghook-shaped members in which said end turns are secured.

1l. In a dynamo-electric machine, the combination of a winding havingend turns, and a plurality of interiitting bracing mem` bers each havinga hook-shaped portion in which the outer portions of said end turns aresecured. i

l2. In a dynamo-electric machine, the combination of a winding havingend turns, and circumferentially spaced interfitting members havinghook-shaped ortions in which said end turns are securedl 13. In adynamo-electric machine, the combination of a winding having end turns,and circumferentially spaced interiittin members supported radiallyoutward Wit respect to said end turns and having hookshaped portionslooping around the outer portions of said end turns to support saidend-turns.

14. In a dynamo-electric vmachine, a frame, a core supported thereby,said core provided with a winding having end portions extending beyondsaid core, and means for supporting the end portions in iixed positionrelative to said core comprising members having both radial and axialadjustment.

In testimony whereof we affix our signatures, in the presence of twowitnesses.
